Well been on for 15 mins & I would say hes really (and your own words) it up.
When you die you respawn invisible so other players can't see you only way to fix this is to logout & rejoin.
But what happens if the server is then full & you can't carry on playing. (not thinking of our 24 man server but other servers)
So your forever seeing name left server, name joined server, then theres a chance of death on respawn your then invisible again so you got to logoff rejoin.
Also while invisible you could be a right dick (like I was
) & attack & kill a fellow player they can't do anything about it as they don't know who killed them.
